Patented May 3, 1932 UNITED STATES PATENT OFFICE EDWIN A. OLLEY, OFSYRACUSE, NEW YORK, ASSIGNOR TO OROUSE-HINDS COMPANY, OF SYRACUSE, NEWYORK, A CORPORATION OF NEW YORK FUSE PLUG PANEL AND BLOCK Applicationfiled March 7, 1928. Serial No. 259,627.

This invention has for its object a fuse plug block which isparticularly simple in construction and readily applicable to a paneland by which several difierent combinations of wiring can be readilymade.

The invention consists in the novel features and in the combinations andconstructions hereinafter set forth and claimed.

In describing this invention, reference is bad to the accompanyingdrawings in which like characters designate corresponding parts in allthe views.

Figures 1 and 2 are respectively a plan and end elevation of this fuseblock and the panel on which it is mounted.

Figure 3 is an inverted view of the block.

Figure 4 is an end elevation, partly in section of parts seen in Figure3, the section be ing taken on line 44, Figure 3.

Figures 5, 6, 7, and 8 are diagrammatic views of the differentcombinations of wir- I designates the panel and 2 the block, these beingof insulation.

3 and 4-. designate respectively the outside bus bars, these beingmounted on the lower side of the block 1 and arranged substantiallyparallel to each other and being located in channels 5, 6 in the block.T he block is preferably formed with a lengthwise passage therethroughand the bus bars 3, 4 are located on opposite sides of this passage 7.

8 is a third bus bar having branches 9, 10

overlying horizontal ledges 11 and 12 on the lateral sides of the blocklocated midway between the top and bottom of the block, the branchesbeing secured to the block by screws 13 extending upwardly from thelower side of the block into the branches.

14, 15, 16 and 17 designate fuse receptacles mounted on the block, theterminals 18 and 19 of each receptacle being mechanically andelectrically connected respectively by screws 20 and 21 to one of theoutside bus bars 3, 4 and to one of the load circuit bars and hencebeing mechanically secured by the screws 20, 21 to the block.

22, 23, 24 and 25 designate load circuit bars mounted on the lower sideof the block 2 and extending beyond the lateral sides thereof,

these being arranged substantially flush with the lower face of theblock 2, the load circuit bars and also the branches 9, 10 of theneutral bar are provided with suitable wire binding devices 26, 27.

The block is mechanically secured to the panel 1 by screws 28 extendingthrough the panel from the rear side thereof and threading into holes 29in the load circuit bars. The screws 28 thus mechanically secure theblock to the base and the screws 20 and 21 mechanically secure theoutside bus bars and the load circuit bars and the fuse to the block aswell as electrically connect the fuse terminals with the bus bars andthe load circuit bars.

Owing to the relative arrangement of the bus bars, load circuit bars andfuses, these parts are compactly located on a comparatively small blockand several wiring combinations are possible.

In Figure 5, a two circuit two wire double fuse combination is shown inwhich one leg of the load circuit is connected to the load circuit bar23 and the other leg to the load circuit bar 25, and the one leg of theother circuit is likewise connected to the load circuit bar 22 and theload circuit bar 2&, the circuits being designated with the numerals 1and 2 at the fuses in said circuits.

In Figure 6, a four circuit two wire single fuse combination is shown,the circuits being numbered 1, 2, 3, 4 at the fuses in said circuit. InFigure 6, one leg of the load circuit is connected to the load circuitbar 23 and the other leg to a binding device on the branch 9 of the busbar 8. The other three load circuits are likewise connected to the loadcircuit bars 22 and branch 9, load circuit bar 2& and branch 10 and loadcircuit bar 25 and branch 10.

In Figure 7, a two circuit two wire double fuse combination is shown inwhich the legs of the load circuit are connected respectively to theload circuit bars 24, 25 and to load circuit bars 22, 23.

In Figure 8, a four circuit two wire single fuse combination is shown inwhich each leg of the load circuit is connected to one of the loadcircuit bars 25 and to one of the branches of the third bus bar.

What I claim is:

1. In a fuse plug panel and block, the combination of a base, a blockmountable on the base, a pair of substantially parallel outside bus barsmounted on the lower side of the block, the block also having a ledge011 opposite sides thereof and a neutral bus bar having branches on saidledge, load circuit bars mounted on the lower side of the block at anangle to the outside bus bars, fuse plug terminals mounted on the blockand means for electrically and mechanically connecting the members ofeach pair of terminals'to one of the outside bus bars and to one of theload circuit bars.

2. In a fuse plug panel and block, the

combination of a base, a block mountable on the base, a pair ofsubstantially parallel outside bus bars mounted on the lower side of theblock, the block also having aledge on opposite sides thereof and aneutral bus bar having branches on said ledge, load circuit bars mountedon the lower side of the block at an angle to the outside bus bars, fuseplug terminals mounted on the block and means for electrically andmechanically connecting the members of each pair of terminals to one ofthe outside bus bars and to one of the load circuit bars, the outsidebus bars, and the load circuit bars being substantially flush with thelower side of the block and screws extending through the base andthreading into some of said bars for mechanically securing the block tothe base.

3. In a fuse plug panel and block, the combination of a base, a blockmounted on the base, a pair of substantially parallel outside bus barsmounted on the lower side of the block, the block also having a ledge onoppo- 1 site sides thereof and extending parallel to the outside busbars, a neutral bus bar having terminals on said ledges, load circuitbars mounted between the base and the block at an angle to the outsidebus bars and extending and having terminals beyond the edges of theblock, fuse receptacles carried by the block, each fuse receptaclehaving one of its terminals mechanically and electrically connected tothe outside bus bar and its complemental terminals mechanically andelectrically connected to the load circuit bar, and means extendingthrough the base and coacting with the load circuit bars for securingthe block to the base.

In testimony whereof, I'have hereunto signed my name, at Syracuse, inthe county,

of Onondaga, and in the State of New York. this 15th day of December,1927.

EDWIN A. OLLEY.
